Confirm the problem in Intrepid 8.10 running on eee 901. After initial
install, both xrandr -q and System-->Preferences--> Screen Resolution
detect the external monitor, but report incorrect maximum resolution
1024x768 for the monitor capable of 1280x1024.

Changing Virtual in /etc/X11/xorg.conf and restarting X solves the
problem:

The bug can be confusing for a user, because it creates an impression of
graphic card or monitor being incapable of higher resolutions (resolutions
higher than virtual are not shown at all).

[Needs GEM] higher resolutions aren't recognized for external monitors after
hotplugging but after X start (Virtual is static)
